Describe how traits are inherited through traits sexual Reproductions WILL MARK AND 5 STARS

1 answer:

5 0

Answer: sexual reproduction is the union of male and female gametes to form a fertilized egg, or zygote. The resulting offspring inherit one half of their traits from each parent. The process where haploid sex cells are created from diploid parents is called meiosis, and it occurs only in the reproductive organs.

Montano1993 [528]

Answer:

Length of the cells = diameter of field of view/ number of cells across the field of view

Explanation:

therefore 2.25= 4.5*X

X= 2.25/4.5

=0.5 number of cells

alexandr402 [8]

Answer:

given, mother and father are heterozygotes.

let, father has B blood group and mother has A blood group.

then their heterozygous genotypes are --

father = iB, iO and mother = iA, iO

punnett square will be,

iB iO

iA iA iB iA iO

iO iB iO iO iO

the genotypes of their progeny will be, iAiB , iAiO ,iBiO and iOiO

and phenotypes will be 3 are heterozygous and 1 is homozygous.

Three lots with parallel side boundaries extend from the avenue to the boulevard as shown answer

larisa86 [58]

Three lots with parallel side boundaries extend from the avenue to the boulevard as shown in the diagram attached.

Given;
x + y + z = 140 meters

According to the proportion theorem,

$\frac{x}{40} = \frac{y}{30}$

Solving for x, using cross multiplication:

$\frac{x}{1} = \frac{40y}{30}$

Similarly,

x/40 = z/35

solving for z by cross multiplication,

z = 35x/40
z = 7x/8

Now, the third proportions,
y/30 = z/35

Solving for y,

y = 30z/35
y = 6z/7

x + y + z = 140

4y/3 + 6z/7 + 7x/8 = 140

(224y + 144z + 147x)/168 = 140

224y + 144z + 147x = 23520

Substitutoing z = 7x/8,

224y + (144 × 7x/8) + 147x = 23520

224y + 126x + 147x = 23520

224y + 273x = 23520
Now,
Substitute y = 3x/4

(224×3x/4) + 273x = 23520

168x + 273x = 23520

441x = 23520

x = 53.33

Now,
We know that
y = 3x/4
so,
y = 40

And,
z = 7x/8
Z = 46.66
